IMPROVEMENT iN LUBRICATING-CUPS.

Specification forming part of Letters Patent No. 138,555, dated May 6, 1873,' application tiled January 30, 1873.

To all whom it may concern:

Be it known that I, THEODORE COOPER, of Warwick, in the county of Kent and State of Rhode Island,`have invented a certain new and useful Improvement in Oil-Oups for Lubricating Shafting and other purposes, of which the following is a specification, ret'erring to the accompanying drawing making a part of the same, in which- Figure A is a side elevation of my improved oil-cup for lubricating shafting. Fig. B is a like view of the same as used for lubricatin g certain parts of a locomotive-engine. Figs. G and D are vertical transverse sections, respectively, of Figs. A and B. Fig. E is a plan of the cover of the cup, showing the device for graduating the flow of oil from the cup. Fig. F is a vertical transverse section of the journal-box of a railroad car provided with my improved oil-cup. Fig. G represents my invention applied to an oil-cup to be carried in the hand.

My invention relates to the combination of, a regulating and graduating apparatus with a reservoir and a siphon .for delivering their bricating liquid therefrom in such a manner that the quantity of the liquid delivered by the siphon may be adapted to the requirements of the parts to be lubricated"`and by means of the graduating device such quantity may be indicated and determined, the object being not only to regulate the ,dow of oil, but to be able, by means of the graduating device, to determine the exact quantity to be supplied. y

In the drawing, l is the reservoir, which may be of metal, in the form of a cup, as shown in Fig. A, or it may be of glass inclosed in a metallic cup having Openings through which the VquantityY of oil in the glass reservoir can be The siphon consists of an inner tube, 6, rising from the bottom of rthe reservoir, and an outer tube, 5, of larger diameter inclosing tube 6 and running nearl to the bottom ot" the reservoir. The top oil the outer tube is closed, and, as described, forms the short end of the siphon, The inner tube passes through the bottom of the reservoir and forms the long arm of the Siphon. The closed end at the top of the outer tube forms a valve, and the open end of the inner tube beneath forms a seat for said valve.

The adjustment of the valve with its seat is the means by which the flow of oil is regu- Y lated. The extent of opening between the said valve and seat is graduated by means of a wedge-shaped washer, 2, turning upon an inclined surface beneath it in such a manner that when `the thicker part of the washer is upon the elevated portion of the inclined surface, the valve is lifted from its seat; and when, on the other hand, the thicker portion of the washer is upon the lower portion of the said inclined surface, the valve is depressed relatively to its seat by means of a spring, 4, surrounding the cuter tube and exerting a consta-nt pressure between the shoulder on said tube and the under side of the cover of the cup to force the tube 5 down.

By this arrangement of parts it will be seen that, by turning the washer half a revolution, the valve is elevated or depressed from one extreme to the other of its openingand by means of a suitable index or pointer, 3, which sweeps over a graduated surface on the top of the oil-cup, the position of the valve and the extent of its opening are readily indicated and determined. The position of the washer on the outer tube 5 is adjusted by means of a nut, 8, and secured in its position by a checknut, 1l, at the top. 9 is a vent or Opening from the top through the center of the outer tube for the introduction of air into the reservoir for the proper operation of the siphon before described.

The Operation is, that the proper quantity of oil is supplied to the reservoir, from which it ascends in the space 10 between the two tubes of the siphon, and descends through the inner tube or long arm 6 to the bearing to be lubricated, the quantity so discharged through the long arm of the siphon being determined by the opening of the valve, the/ extent of which is determined by the nut /to yield the maximum quantity. The nut isset in its position by the check-nut 11, after which the supply is graduated by turning the washer 2 tO close the valve, the index-tin ger indicating the extent of Opening and the quantity supplied.

Having described my invention and its operation, I do not claim a reservoir having a siphon formed of an inner and an Outer tube, as the same is old and Well known. Neither do I claim broadly in combination With such reservoir and siphon a device for regulating the flow of Oil, as this is not new; but

What I claim as my invention is- The combination of the regulating and graduating apparatus, consisting of the spring 4, the Washer 2, the nut 8, and the index 3 or their equivalents With a reservoir and a siphOn, arranged and operating substantially as shown and described.
